Brief Summary:
Phase 3 multicenter, open-label study of safety, tolerability, efficacy, and pharmacokinetics (PK) of ProMetic's Immune Globulin Intravenous (Human) 10%, the investigational medicinal product [IMP]), in Adults and Children with Primary Immunodeficiency Diseases (PIDD).

Primary Immunodeficiency Biological: Immune Globulin Intravenous Biological: Prometic's Immune Globulin Intravenous 10% Phase 3

Detailed Description:

This is a pivotal Phase 3, open-label, single-arm, multicenter study to assess the tolerability, safety, efficacy, and Pharmacokinetics of the Investigational Medicinal Product in adults and children with Primary Immunodeficiency Diseases (PIDD). A total of approximately 75 subjects aged 2-80 years will be enrolled in the study. Subjects who switch from an investigational immune globulin or subcutaneous immune globulin (IGSC) are required to receive a stable dose of commercial product (CP), which is a licensed commercially available immune globulin intravenous (IGIV) product for at least 3 cycles before they can be given the Investigational Medicinal Product . This study schema will result in the Commercial Product Treatment Period and Investigational Medicinal Product Treatment Period. All subjects will be treated on an outpatient basis with the Investigational Medicinal Product for approximately 1 year, with the dose and schedule based on their previous IGIV treatment regimen (21-day or 28-day dosing interval). A subset of subjects will participate in a Pharmacokinetics sub-study.

The primary objective of the study is to examine the rate of clinically documented serious bacterial infections (SBIs) in subjects treated with the Investigational Medicinal Product to achieve a rate of less than one SBI per year.

Primary Outcome Measures :
  1. Annual Rate of Occurrence of Serious Bacterial Infections (SBI) [ Time Frame: One year ]
    SBIs were calculated for each subject as 52n/w, where n is the number of reported SBIs and w is the number of weeks on study. For the combined cohorts only, a 99% one-sided (upper) confidence limit for the incidence rate of SBIs (scaled to represent 12 months exposure if necessary) was derived, and the objective of demonstrating that the true infection rate was below 1 per subject per year was considered established if this upper limit was less than 1. To calculate the confidence limit, a negative binomial regression model will be used. This model includes an overdispersion parameter to account for possible intra-subject correlation as well as the actual time period each subject is on the study as an offset variable.

Secondary Outcome Measures :
  1. Trough Levels of IgG (Total) Prior to Each Prometic IGIV 10% Infusion [ Time Frame: One year ]
    Subject's total IgG levels will be assessed prior to each Prometic IGIV 10% infusion
